Mr Arcturus Black requests the pleasure of [name's] company at home for an Extraordinary Garden Party on the afternoon of March 2nd. There will be a cream tea and sundry outdoor amusements, magical and otherwise, to celebrate the arrival of the Spring. Formal day dress requested.
[These carefully handwritten (with his quill!) invitations are on parchment inside little envelopes. They're delivered to the homes of all Arcturus' friends, and friendly acquaintances from the magic classes. The names of spouses and children are included if he's aware of them, but there are no general 'plus one' invitations. (Unmarried couples would not be invited together, because he's old fashioned, but poke me if you need a workaround.) I'm doing it this way and not writing a list so I don't accidentally leave people out - he wouldn't invite people he doesn't know or like, or thinks wouldn't enjoy the event, but beyond that you're welcome to assume your character got one! Reply to him here if you want, and/or to the event thread on the day.]
